The hottest wheat starch and its straw fiber will

Wheat starch and its straw fiber will become new fast food packaging materials
over the years, fast food has used various materials as outer packaging to realize the development strategy of one body and two wings, and for one reason or another, each material has proved to be problematic. However, according to the research results recently submitted at the meeting of the American Chemical Association, researchers finally found a better, cheaper and more environmentally beneficial aluminum alloy fast food packaging method with its excellent performance
foreign reports said that at first, most fast food was packed with polystyrene clam shells. This material is light and easy to make, and it can also maintain the temperature of food. Unfortunately, polystyrene cannot be degraded. It also contains chlorofluorocarbons that destroy ozone. Considering that these materials have the defects of polluting the environment, the fast food industry turns to cardboard, but cardboard also has disadvantages. Jeffrey nobys of the Ministry of agriculture of the United States said, "cardboard is more expensive, heavier, more complex to make, and it does not keep warm."
therefore, nobys and his colleagues in the Ministry of Agriculture began to look for a better material. They concluded that the prospect of packaging with wheat - that is, using the fiber of wheat straw and the starch in wheat grains - was good. The wheat packaging box can be completely degraded. "If people have a compost pile in their backyard, they can throw these boxes into the compost pile," nobys stressed
in the past, people used potato starch to make packaging boxes made of starch, but wheat starch is much cheaper than potato starch. In addition, the packaging box made of wheat starch has a longer heat preservation time than the commonly used cardboard packaging box or the packaging box made of potato starch.
